Abstract Details


To compare optical quality and tear film analysis of normal and dry eye individuals after instilling various lubricating eye drops.


Narayana Nethralaya , Tertiary eye hospital , Bangalore , India


50 eyes of 25 normal individuals and 20 eyes of 10 dry patients were studied using advanced imaging tools like LipiView Interferometer (TearScience Inc, Morrisville, North Carolina, USA) ,Noninvasive TBUT ,Modulation transfer function and Mean OSI using OQAS( HD Analyser). These patients were subjected to randomized use of A(Polyethylene Glycol 400 NF 0.4% , Propylene Glycol 0.3%) ,B( Sodium Carboxymethyl-cellulose 5mg, Stabilized Oxychloro complex 0.1mg, C (Sodium carboxymethyl-cellulose -5mg), eye drops and the optical quality and tear film at 5 mins and 40mins after applying the drops were assessed.


After 5 and 40 mins all the indices suggested that the Avg ICU was -78.23 72.33, 71.2, and with drops A, B, C respectively , which suggested that the drop A had a beneficial effect on the lipid layer. The optical scatter index, modulation transfer function and the mean OSI also showed a improvement after the similar drops in both normal and dry eye individuals.


Significant improvement in the optical quality and tear film parameters were seen with the eye drops A.
